These hoops fit underneath the bed with a 1″ body-lift with minimal trimming (they are designed to mount in the center of the frame) or no trimming with a 2″ body lift. They mount just fine on an Early Bronco with no body-lift but would mount lower on the frame.
VIF rear Shock Hoops are specificly designed to be used with a reservoir shock and a limiting strap, however standard shocks can be used as well.
The material is 1.5″ x .120 tubing and 1″ x .250 DOM on the shock mount.
PLEASE NOTE: The factory lower mounts are re-used by carefully removing them with a cut-off wheel (I don’t recommend a plasma or torch) then placing them on the front of the rear end
